SPECIFICATION forming part of Letters Patent No. 744,856, dated November24;, 1903. Application filed May 6, 1903. Serial No. 155,875. (Nomodel.)

To rtZZ whom, it Ina/y concern.-

Be it known thatI, JAMES MAXEY BROOKS, a citizen of the United States ofAmerica, and a resident of Molena, county of Pike, State of Georgia,have invented certain new and usefullmprovements in Wheel-Scrapers,ofwhich the following is a full, clear, and exact description, referencebeing had therein to the accompanying drawings, in which Figure 1 is aperspective View of the machine loaded; Fig. 2, a plan View of the same;Fig. 3, aside view of the same, the near wheel being removed; Fig. 4:, aview in detail showing the position of some of the parts while in theact of dumping; Fig. 5, a detail perspective of the end gate; Fig. 6, aview of the machine in the act of loading, the near wheel being removed;Figs. 7, 8, 9, and 10, detail views hereinafter described; Fig. 11, aside elevation showing the manner of connecting a pair of scrapers whenused in tandem; Fig. 12, a detail perspective of the frame used inconnecting the scrapers when used in tandem; and Fig. 13, a sideelevation showing the apparatus converted into a log-cart, the

near wheel being removed.

The object of this invention is principally to improve the loadelevating and dumping devices and also to render the machine readilyconvertible into a tandem excavator,a log'cart, a two-wheeled dump-cart,and a wagon, thereby especially adapting the machine for generalcontracting-work.

The invention also has other objects in view, which will appear in thecourse of this specification.

Referring to the drawings by reference-letters, the draft applianceconsists of a tongue 0., attached at its rear end to a cross-bar b,which is braced to the tongue by the draftbars 0, which are long enoughto extend back to the rear of the arch of the axle d and are eachprovided with an upward-extending arm e at its rear extremity, thesearms extending up above the spindles of the axle and being pivotallyconnected by removable horizontal bolts f to the rear ends of side barsg, which are parts of a frame or yoke consisting of said side bars and afront crossbar h.

The side bars g are rigidly attached to the vertical parts of the archof the axle and are braced by the forwardly-inclined braces 2', rigidlyconnecting the bars 9 to the axle-spindles, whereby said frame and theaxle move as a single frame.

Journaled in suitable brackets j, attached to the side bars 9 near thefront bar h, is a rock-shaft 70, extending entirely across the front ofthe machine parallel to the front bar h, and rigidly attached to thisrock-shaft is a stop I, which engages under the bar It and limits themovement of said shaft. The ends of said shaft beyond the side bars 9are formed into cranks m, which carry brakeshoes n, which are adapted tobear upon the tires of the Wheels. One end of said shaft carries anoperating-handle 0, which lies outside of one of the transporting-wheelsand extends toward and a little below the hub thereof to be withinconvenient reach of the driver, who usually Walks along by the side ofthe machine.

Pivoted to the front bar It is a latch 19, which is adapted to normallyengage under the projecting edge of a plate q, bolted on the rear end ofthe tongue, and whose handle 1" extends toward one side of the machinefar enough to be reached by the driver without passing in front of themachine.

The scraper-pan s is pivotally hung about midway its length by verticalhangers if, bolted to the side of the scraper and extending up above thetop edges of the same, removable bolts tt being employed topivotallyconnect the upper ends of these hangers to the upturned ends 6of the draft-irons.

The draft-hooks n engage draft-eyes to, attached to the sides of thepan, these hooks inclining upward and forward and being pivotallyconnected by bolts 00 to the draft-bars 0, each hook being provided withan arm y at its upper end which curves upward and rearward and normallyrests upon the rear part of bar 0 and the forward end of a triplever e,which is pivotally supported on a shoulder-bolt .2 between one of thehangers tand the adjacent side of the scraper and whose rear end ispivotally connected at a to a bar b, pivotally supported at c on theside of the scraper and extending rearward beyond the scraper. The baror lever e is slotted at d where its pivot passes through in order thatit may have a limited longitudinal play when it is vibrated on itspivot, and thereby avoid binding.

To the rear end of each of the levers b is pivotally connected a link 6,which extends upward and forward and is pivotally connected to astandard f, loosely attached to the axle-spindle. Each of thesestandards f is provided with a bearing in its upper end, and in thesehearings is journaled a transverse rock-shaft g, whose ends beyond saidstandards are each cranked and provided with a brake-shoe h to engagethe surface of the wheel-tire. One end of this shaft g is provided withan operating handle or lever t", which lies outside of one of the wheelsand extends toward the hub thereof. The han dles 0 and t are preferablyat the left side of the machine.

To limit the depth of the cut, I employ suitable limiting devicesj,connecting the brace tor any other part of the frame carried by the axlein front of the same to the draft appliance. In the present instance Iemploy a chain and a plate 76, pivotally connected to the draft-iron bythe bolt 00, which supports the pivotal draft-hook c, this plate 76'being provided with a series of holes for adjustment purposes; but itwill be observed that I may employ any suitable adjustable devices inlieu of this chain and perforated plate.

In front of each hook o is mounted a downward-inclined bar Z, whichterminates in front of said hook and the eye 10 and in line therewith,and which has its upper end rigidly connected to the draft-irons by oneor more rivets m. The front edge of each of these bars Z may besharpened somewhat, so that they will act as a cutter to cut roots andclods. These bars will also act as fenders to prevent clodsand stonesinterfering with the proper action of the hooks and eyes or loops. Eachof these fenders or colters is braced by an upward and rearwardlyinclined brace 41, connecting it to the draft-iron. This brace n isformed, preferably, by a downward continuation of the rear end of a bar0, bolted to the side of the main draft-irons by rivets m and so. Theforward ends of bars Z are carried around the front corners of thedraftirons and bolted to the tongue, as shown more clearly in Fig. 2,thereby strengthening the weakest points in the draft-ironsnamely, thefront corners thereof.

When the machine is in the act of loading, the parts are positioned asshown in Fig. 6- that is, the draft-hooks u are in engagement with-theloops w and their trip-arms y are oflf the trip-levers z, the levers yand b, which form a sort of toggle-lever, are in alinenient, and thebrake-shoes and their shafts are in the position shown.

When the scraper is loaded and it is desired to elevate the same, thedriver grasps lever 0 and presses it backward toward the hub until thebrake-blocks bear firmly against the wheel-tires, whereupon the forwardmotion of the wheels will carry the arch of the axle upward and theupper end of the frame 9 h downward and forward until-the latch 19engages plate g and latches the forward end of the frame down, whereuponthe driver will release the handle 0. When the forward end of the frameis thus carried down, its rear end is elevated and carries with it theuprights e, on which is hung the scraper, thereby elevating the scraperto the position shown in Fig. 3, latch 13 holding it in that positionwhile it is being transportedto the dumpplace. When the pan is thuselevated, the scraper swings forward and brings the hooks 'v to the rearends of the loops or eyes, as shown in Fig. 3.

In dumping, the driver simply takes hold of lever t" and pulls itrearward to apply the brake blocks h to the wheels, which action carriesthe standards f forward and through the medium of the links a andtoggles Z7 and z lifts the draft-hooks out of the draft-eyes. Thecontinued movement for ward of the standards f then lifts the rear endof the scraper-pan and dumps the pan in the usual way by inverting it.After the pan is dumped it may be readily swung back into the positionshown in Fig. 3 and be then transported back to the loading-place.

When itis desired todrop the pan to load,the driver simply reaches inand releases latch 19, whereupon the scraper drops to loading position.If desired, an end gate 1" may be employed to close the front end ofthis pan when it is elevated. This end gate may be convenientlypivotedupon the side barsg by means of bolts 8', the gate being provided withsuitable side arms t for this purpose and suitable forward-projectinglugs 10', adapted to engage over the front edge of the cross-bar h toprevent the end gate dropping downward too far. Located and supported inthis manner, the

.end gate automatically drops down in front of the scraper when the sameis elevated by the downward movement of the frameg h, as shown in Fig.3. When the said frame 9 his elevated and the scraper-pan drops, thisend gate is lifted out of the way,as shown in Fig. 6;

This machine possesses a number of very important advantages. Animportant feature lies in utilizing the forward motion of the apparatusto both elevate the loaded pan and to dump it and to arrange theoperating-handles at the side of the machine where theywill be withinconvenient reach of the driver, who usually walks along by the side ofthe machine. It will be noted that these handles are arrangedsubstantially radial, so that they are always within easy reach of thedriver no matter what position the brake-shoes may be in. It will benoted, further, that by pivotally hanging the scraper at a point well upand by employing the peculiar arrangement of devices shown and describedfor unlatching the draft-hooks all danger of the pan being prematurelydumped while being transported to the dump-place is avoided, for eventhough the front edge of the pan should engage an obstruction whichwould tend to dump it the draft-hooks would engage the forward ends ofthe draft-eyes and prevent the pan from being dumped, the draft-hookeyes being prevented from missing the draft-hooks by reason of theposition of the draft-ho0ks and the elevated pointof pivotal support onthe pan, as is evident from a glance at Fig. 3.

To convert the apparatus into a log cart or truck, as shown in Fig. 13,it is simply necessary to remove the pan by detaching its bolts to andthe links (2. Then by hitching suitable chains 00 to the arch of theaxle, the same being lowered, and passing said chain under the log to betransported, the front end of the log may be elevated by theelevatingbrakes and latched in that position and be dragged away.

To arrange a pair of scrapers in tandem, as shown in Fig. 11, itissimply necessary to use a supplemental frame y, (shown in detail in Fig.12,) the forward ends of whose side bars are bent up and bolted to thestandards 6, carried by the front machine. This frame extends rearwardbeyond the ends of the bars b and links 6' and is provided with asuitable strap orloop 2', into which the forward end "of the tongue ofthe rear machine may be bolted, this tongue being shortened in orderthat the two machines shall be brought close togetherandbesubstantiallyonemachine. Theframe y is wide enough to avoidinterference with the free operation of the parts of the front machine,so that each machine will be free to operate as when used singly. Thesetandem machines are of great value where the length of the haul is sogreat as to make it advisable to increase the capacityof each machine orenable each team to double its capacity. Of course these tandem machinescan only be employed in earth that is comparatively easyto excavate. Itwill be observed that the forward upward'turned ends of the side bars yare bolted to the uprights e by the same bolts fand u that attach theseuprights to the hangers t and the side bars As shown in Figs. 2 and 3, aseat I) for the driver may be mounted on the roclnshaft g, which thedriver may use while the load is being transported to the dump.

As will be observed, the seat normally inclines slightly downwardly andforwardly, whereby when the driver is in place thereon his weight willtilt the seat up to an approximately horizontal position, and therebyhold the brake-shoes 71. off the wheels.

In addition to limiting the depth of the cut, the chainsj serve anotherpurpose-namely, to lift upward on the draft appliance, and therebycounteract the downward pull on the draft-hooks, whereby the draftappliance will be greatly strengthened.
